*	Phase 5: Fix MDEV creation blocker - mdev parent registration & ioctl-based ↵	Arthur Hanson Rasmusson	2026-09-13
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	vGPU type registration - Implemented nv_vgpu_mdev_register_parent() using mdev_register_parent() API with nv_vgpu_mdev_types array for proper mdev parent registration - Added ioctl NV_VGPU_IOCTL_REGISTER_VGPU_TYPE for userspace vGPU type registration - Created separate header nv-vgpu-vfio-interface-nvidia.h for nvidia.ko with only extern declarations to avoid duplicate symbol exports - Used KBUILD_EXTRA_SYMBOLS to provide only needed symbols (nvidia_vgpu_vfio_) - Updated create_mdev.sh to use correct mdev type names (pci-nvidia-vgpu-) - Updated load_vgpu_stack.sh to load open-iov-vfio.ko before nvidia.ko Result: 4 mdev types now show available_instances=8, mdev creation successful
*	Initial commit: Open-IOV vGPU-IO complete stack	Arthur Hanson Rasmusson	2026-09-13
	- Firmware decompilation: GSP 570.144W (28.5MB ELF, RV64IMAC), 132 decompiled C files - Kernel modules: nvidia.ko (34MB, OpenRM), open-iov-vfio.ko (2.8MB, VFIO mdev), gsp-vgpu.ko (1.8MB, guest driver) - Userspace: libiov.so/libvgpu.so (76KB), example_vgpu (28KB), rpc_emulator.c - PCI config space emulation (256B with PM, MSI, MSI-X, PCIe caps) - 12 RPC types fully mapped from firmware decompilation - BAR trap, WPR, scheduling, notification, migration emulation - Helper scripts: load_vgpu_stack, create_mdev, launch_qemu_vgpu, test_vgpu_stack, setup_guest_driver, unload_vgpu_stack - Architecture documentation - Wiki: 10 technical documents - Git LFS for large binaries (.ko, .bin, .iso, .img, .o, ghidra repos) - nvidia-open-gpu-kernel-modules as submodule
